FREDERICK DIETZ, OF NEW YORK, N. Y., ASSIGNOR TO R. E. DIETZ COMPANY, OF NEXV YORK, N. Y.

LAMP-SOCKET.

To all fr0/1.0m t muy concern:

Be 1t known that l, FREDERICK Dnrrz, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in Lamp-Sockets, oit which the following is a specification.

rlhis invention relates to that class oit sockets which are applied to lamps, lanterns and other articles for attaching the same to a supporting prop, holder or standard. rlhesc props or holders are sometimes round in cross section and sometimes rectangular, oblong or flat and connection is impossible when the lamp or lantern has a flat socket while the prop is round, or vice versa.

The object of this invention is to provide a simple, convenient and cheap socket which is suitable for connection with either 'form ot prop.

In the accompanying drawings: Figure 1 is a front elevation, Fig. 2 a vertical section on line 2--2, Fig. 1, Fig. 3 a rear elevation, and Fig. l a top plan view of this improved socket. Fig. 5 is a perspective view of the same attached to a round prop. Fig. (i is a top plan view of a modilied form of the socket. Fig. 7 is a perspective view of a 'flat prop.

Like reference characters reifer to like parts in the several figures.

Referring to Figs. 1-5 and 7, the body of the socket comprises a round front portion A of the proper shape to fit upon a round prop B, and a llat or rectangular rear portion C of the proper shape to tit upon a flat or rectangular prop D. The round prop B rises from a horizontal arm Z) which is provided with an attaching clamp ZJ, and the flat prop D rises from a horizontal arm l provided with an attaching flange cl.

The round -l'ront portion A and the flat rear portion C of the socket are formed integrally, preferably of sheet metal, and the cavities of the two portions communicate, so that the round front portion is partially open at the rear, in a circumferential direction, the junction points e between the Jfront portion and the rear portion being on opposite sides of an upright slot or opening by which the cavities communicate. The curvature of the front portion is suiliciently greater than a half circle to cause this portion to seat itself rmly upon a round prop.

The rear Wall of the fiat portion C is Specification of Letters Patent.

composed of two upright parts f which extend inwardly from the side edges ot the rear portion but are not oined together, being separated by an open space g. Each part of the rear wall is provided at its upper and lower ends with a lip 7L which is inserted in a slit in the plate or wall Il of the lamp, lantern or other article to which the socket is secured and which bent over or clenched on the opposite side, as represented in Fig. Q. These lips are represented by dotted lines in Fig. 3 in the flat or unbent position.

The socket pre'lerably tapers upwardly in order to enable the same to seat itself lirmly upon the prop which is similarly tapered.

When the socket is made oil sheet metal or other llexible material, the round portion as well as the flat portion is capable of springing or yielding somewhat in applying the socket to the prop, whereby a close tit may be secured and rattling be prevented, even il the socket and prop are not exactly of the same size or form.

The round portion is preferably provided in its lower edge with an approximately semi-circular recess z' which permits the socket to extend down on both sides of the horizontal arm b of the round prop, as represented in Fig. 5, so that the round portion straddles this arm, whereby the socket is prevented from turning on the prop. This security against turning may be still further increased by providing the prop near its junction with the horizontal arm with an upright rib or lug 7: and the socket with a corresponding elongated recess Z which extends upwardly from the recess z' and into which this rib engages.

In the modified construction of the socket represented in Fig. (S, the front portion M is hall round and the flat rear portion N is so shaped that the round prop, indicated by a dotted line, is contincd in the hall round portion by the plate or wall O of the lamp or lantern to which the socket is secured and which forms the rear wall o the socket. In this construction the side pieces p of the socket are turned outwardly and are secured to the wall O by rivets or other suitable means.

I claim as my invention:

l. A flexible attaching socket for lamps, lanterns and other articles comprising a rounded front portion and a flat rear portion which have communicating cavities, the

rounded front portion adapted to ita round prop and the flat rear portion adapted to tit. a fiat prop, said socket having flat front.' 5 walls which extend outwardly from the-rear edges of the rounded front portion, side walls which extend rearwardly from, the

outer ends of said ilat front walls, and separated attaching flanges -wh-ichl extend i0 from the rear ends of said side walls parallel with said lat'front walls,- substantially.
